1. The Structure of ‘Love Never Dies’

Although it suffers from a weak story, the musical “Love Never Dies” has some beautiful music and has obvious parallels to its predecessor, “The Phantom of the Opera.” Among the borrowed tropes are a Phantom solo in the first act (“‘Til I Hear You Sing”), Christine’s big second-act solo (“Love Never Dies”), a rock-influenced duet in the first act (“The Beauty Underneath”) and an erotic duet between the Phantom and Christine (“Beneath a Moonless Sky”).

2. The Outro of ‘Look With Your Heart’

In “Love Never Dies,” the music box melody at the end of this number (which signals the Phantom’s quiet entrance) is the identical opening melody of “The Point of No Return” in “The Phantom of the Opera.”

3. The Song ‘Love Never Dies’

A more appropriate title might be “This Song Never Dies.” The song’s melody debuted as “The Heart Is Slow to Learn” in 1998 at a Royal Albert Hall celebration of Lloyd Webber’s music. The chorus melody was then recycled as “Our Kind of Love” for Lloyd Webber’s musical “The Beautiful Game.” The song’s third and final form was as the title song for “Love Never Dies” in 2010.

4. The Song ‘Music of the Night’

The song “The Music of the Night” from “The Phantom of the Opera” was the subject of controversy after the estate of Giacomo Puccini filed a lawsuit against Lloyd Webber. Puccini’s estate had argued that the melody in the lyrics “Silently the senses abandon their defenses” was stolen from an excerpt of the opera “La Fanciulla del West.” The lawsuit was settled out of court. Lloyd Webber had originally planned to use the melody for “The Music of the Night” under different lyrics for his show “Aspects of Love,” but that song, titled “Married Man,” was cut from the final version of “Aspects.”

5. The Song ‘Make Up My Heart’

Speaking of Puccini, the opening riff of this song from “Starlight Express” is almost identical to the opening of “Musetta’s Waltz” from Puccini’s “La Boheme.”

6. The Title Theme From ‘The Phantom of the Opera’

The chromatic title theme of Lloyd Webber’s most famous musical is eerily similar to a certain riff from Pink Floyd’s song “Echoes.” The band’s bassist at the time, Roger Waters, never sought legal action, claiming that “life’s too long to bother with suing” Lloyd Webber. Some people have even pointed out similarities to the intro of Debussy’s “Prelude to the Afternoon of a Faun.”

7. The ‘Mirror Scene’ From ‘The Phantom of the Opera’

The line, “I am your Angel of Music” sounds suspiciously similar to a passage (skip to 1:20) from “The Battle on the Ice” from Sergei Prokofiev’s “Alexander Nevsky.”

8. The Song ‘I Don’t Know How to Love Him.’

Mary Magdalene’s solo from “Jesus Christ Superstar” has been scrutinized for sounding too similar to the Andante movement from Mendelssohn’s “Violin Concerto in E Minor” (skip to 0:33).

9. The Song ‘Memory’

“Memory” from the musical “Cats” has been noted for its similarities to the main melody in Maurice Ravel’s “Bolero.”

10. ‘King Herod’s Song’ and ‘Try It And See’

The melody to “King Herod’s Song” from “Jesus Christ Superstar” was originally taken from “Try It and See,” which Lloyd Webber wrote for the Italian rock singer Rita Pavone.

11. The Duet ‘All I Ask of You.’

The classic duet from “The Phantom of the Opera” was originally a solo that Lloyd Webber wrote titled “I Don’t Talk to Strangers,” recorded by opera superstar Plácido Domingo.

12. The Song ‘’Til I Hear You Sing’

The Phantom’s solo from “Love Never Dies” borrows a melody from “If Not For Me, For Her” from Lloyd Webber’s “The Woman in White.” The Phantom’s melody for “And sometimes at nighttime, I dream that you are there” is almost identical to Marian’s lyrics “I know that I’ve wronged you, and that I can’t defend.”

13. The Song ‘As If We Never Said Goodbye’

In Norma’s big solo from Lloyd Webber’s “Sunset Boulevard,” the melody for the lyrics “I don’t want to be alone / That’s all in the past” is identical to the original version of “Half a Moment” from “Jeeves.”

14. The Song ‘If This Is What We’re Fighting For’

The opening for this solo in Lloyd Webber’s “The Beautiful Game” is almost identical to “Will This Last Forever?” from his show “The Likes of Us,” which was written in 1965 but not performed until 2005.

15. The Entire ‘Variations’ Set

Lloyd Webber’s “Variations” set (1978) is based on the theme from Paganini’s 24th Caprice, a virtuoso showstopper for classical violinists.
